ile it known that l, GEORGE ll. NEWELL, a citizen of the United States,residinCr at Grand Rapids, in the county of Kent anu State of Michigan,have invented certain new and useful Improvements in Projectiles; and Ido hereby declare the followingto be a full, clear, and exactdescription of the invention, such as Will enable others skilled in theart to which it appertains to make and use the same.

My invention rela-ies to improvements in projectiles; and its object isto provide a projectile having allot' the advantages of a patch ofporous material to wipe and lubricate the bore of the gun-barrel and ofa strong metal lic jacket to hold the soft-metal body'froin changingform upon impact with the target or unduly expanding in the gun underthe sudden impulse of high explosives andto hold -jinuoh to be Whollyfof these objections and secure a highly-satisto theiands of the barreland follow the twist of the saine under the high pressure of highexplosives, to effectually secure the jacket in place on the projectile,and to provide the device fwith certain neu7 and useful featureshereinafter more fully described, and particularly pointed out in theclaims.

Heretofore iti has been proposed to apply a patch of clot-h or othersuitable material to the body of a soft-metal projectile, securing theends only. These are not suftiy secured and. in use are torn ed moreoriess, and the remaining fragments seriously interfere with the flightof the projectile. Furthermore, such patches have no tendency torestrain the soft-metal body from expanding and for these reasons arepractically a failure. It has also been proposed to Wind the soft-metalprojectile spirally with wire of harder and stronger metal. Thesewindings, while serving to hold the body from expanding, areobjectionable in that they cannot be properlylubricated, and themetallic Contact ofthe Wire heats and cuts the gun-barrel toosatisfactory. l avoid all factory result by mal-:ing the body of theprojectile of lead or other suitable soft metal and applying to thesurface thereof a lubricated patch or covering of cloth, leather, orother suitable porous and yielding material, winding at intervals aroundthe same a suitable wire of soft steel, copper, or other strong andyielding metal, securing the ends thereof in any suitable manner, andsecuring each coil of the same by embeddingJ it in the bodyf thelprojectile. l

Referring to the accompanying drawings, Figure l is an enlargedsideelevation of a pro jectile embodying myinvention; Fig. 2,alongitudinal section of the same, taken throughthe axis thereof; andFig. 3, an enlarged detail in section, showing the Way the Wire isembedded in the projectile.

Like letters refer to gures.

A is the body of the of lead.

Bis a patch or covering of clorh,thin leather,` or'other suitableyielding material, lwhich may be saturated with any suitable lubricant.

C is a Wire wound spirally on the outside of the patch and havin g itscoils separated a suitable distance so that the patch will projectbetween the coils of Wire and engage the surface of the bore of thegun-barrel. The space between the turns of wire may be varied somewhataccording to the service required of the projectile, but should be openenough topermit the patch to project and contact the grooves of thegun-barrel between each turn of the Wire and close enough to eiectuallycoming loose and to also effectually prevent expansion of the soft-metalbody under the impact of high explosives and contact with the target, l

The ends of the patch and of the wire may be secured in any suitablemanner, the means of securing the ends of these forming no part of mypresent invention.

To eifectually secure each separate coil of the Wire, whereby it willnot become detached if broken and will not move longitudinally on theprojectile, it is embedded in the surface of the projectile to such anextent that it lies wholly Within the plane of the same, and the metalof the projectile surrounds it suficiently to hold it from detachmenteven though it should be broken. This is preferably done by firstwinding the Wire around a cylindrical blank of less diameter than theproposed finished projectile and then by a suitable die or swagecompressing it longitudinally, whereby the soft met-al of the bodyprojectile, preferably like parts in all of the` IOG expandsvlaterally'between the turns or coils of the wire and closes around thewire by contact with the wall of the swage, assuming substantially theform ,shown in Fig. i). This tightens 'the wire and patch about theprojectile and at the same time effectually secures the wire in place.The wire and the patch adjacent 'thereto thus lie in a spiral.depression in the body A, and both the patch between theturns of Lthewire and the Wire yitselfk engage the gun-barrel, the wire also servingto secure the patch in place and prevent its leaving the projectile. Thewire also prevents undue expansion of the body of the projectile and,directlyengaging the lands of the gunbarrel, more readily yields andconforms to the shape thereof than a solid shell or jacket oflikematerial and at the same time has a sufficient hold when under highpressure to follow the twist of the barrel. My projectile does not heator cut the barrel because of the lubricating and wiping action of thepatch between each turn of the wire. It will also be observed that thereis a slight spaceat each side of the wire to catch and hold anysubstance wiped off the surface of the barrel or any abraded metal fromthe Wire. This also aids in preventing `friction and cutting.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is

l. In a projectile the combination of a sottmetal body, a patch 0Eporous material surrounding the same and projecting between the turns ofwire, to engage the gun-barrel,

and a single continuous wire surrounding the patch and body at frequentintervals, whereby the patch is secured in place throughout the entirelength, and the body held from expanding, substantially as described.

2. In a projectile the combination of a softmetal body, a patch ofporous material surrounding the same and projecting between the turns ofwire, to engage the gun-barrel, a single continuous wire of strong andyielding material wound spirally and at regular and frequent intervalsfrom end to end of said patch, and on the outside of the same,substantially as described.

3. The combination of a soft-metal body, a patch of porous materialsurrounding the same, and a wire of strong and yielding material Woundspirally Afrom end to end on the outside of the patch, the wire andpatch being also embedded in the projectile, and the patch projectingbetween the coils ofthe wire, substantially as described.

In testimony whereof I aiiix my signature in presence of two witnesses.
